NATHAN BAUGHMAN, OF HAMMERSLEY FORK, PENNSYLVANIA.

MowlNc-MACHINE SEAT.

SPECIFICATION forming part of Letters Patent No. 656,337, dated August21, 1900.

Application iled October 9, 1899.

T0 all whom it may concern:

Be it known that I, NATHAN BAUGHMAN, a resident of Hammersley Fork, inthe county of Clinton and State of Pennsylvania, have invented a new anduseful Improvement in Mowing-Machine Seats, of which the following is aspecification.

My invention is an improvement in seats for mowing-machines and the likewherein it is desirable to readily adjust the seat or rock it vfrom sideto side in order to secure the desired level position of the seat whenoperating on hillsides or other inclines; and the invention consists incertain novel constructions and combinations of parts, as will behereinafter described, and pointed out in the claims.

In the drawings, Figure l is a perspective view of a seat embodying myinvention. Fig. 2 is a bottom plan view thereof. Fig. 3 is a front viewof the seat. Fig. 4t is a vertical crosssection on about line 4 4 ofFig. 2. Fig. 5 is a vertical longitudinal section on about line 5 5 ofFig. 2. Fig. 6 is a detail view of the combined supporting bar and rack.Fig. 7 is a detail viw of the seat proper, and Fig. 8 is a detail viewof the pivot-post for the seat.

In carrying out my invention I support the seat A so it can rock fromside to side and arrange beneath it the cam B, which is Inovablehorizontally and extends on opposite sides of the center of movement ofthe seat, so the horizontal movement of the cam will by its inclinedsurface B operate to tilt the seat A in one direction or the other tosecure the desired level position of the seat. The arrangement of thecam to operate horizontally and on opposite sides of the pivotal centerof the seat is important, as if by any accident the detent devicesshould not operate properly there is no danger of the seat swinging downso abruptly on one side or the other as to throw the driver from hisplace.

In the specic construction shown the seat A is provided on its underside with the depending transversely-extending rib C, which is pivotedat its center C to the upper end of the pivot-post D, so the seat A canrock from Serial No. 733,058. (No model.)

side to side. The post D is mounted on the supporting-bar E, which isshaped at its upper end E to form the detent by providing such end withthe edge notches E2 to receive the pawl F, which is carried by the leverG, which is extended from the disk forming the cam B. This cam B ispivoted upon the post D and encircles such post, with its inclined orcam surface B' on all sides of such post and in engagement with thetransverse rib C of the seat A, as shown in Figs. 3 and 4. The lever Gextends to one side of the seat and can be readily grasped by theoccupant of such seat, who can first release the pawl F from engagementwith the notches E2, swing the cam to adjust the seat A to the desiredposition, and then release the pawl F to lock the seat securely in suchposition.

It will be noticed that the construction is simple, compactly arranged,easily operated, avoids all danger to the occupant of the seat, and maybe readily applied to new machines or those already in use.

Having thus described my invention, what I claim, and desire to secureby Letters Fat ent, is

l. The combination of the seat pivotally supported so it can be rocked,from side to side and provided with a depending transverse rib orbearing extending on both sides of its pivot, and a horizontally-movablecam engaging said rib or bearing on opposite sides of the pivot of theseat, and operating and de; tent devices, substantially as set forth.

2. The improved seat herein described com prising the seat properpivoted on an axis extending from front to rear and having a transversebearing extending at right angles to said axis, and the cam extending onopposite sides of the pivot of the seat and engaging the trans= versebearing whereby the earn may rock the seat from side to side but willnot tilt it from front to rear.
